, fication.

This invention relates to needles, and it has more particular reference to needles for knitting and the like, and has for its object to provide a needle for use in connection with threads or yarns. and which by proper manipulation results in the weaving or knitting ot a textile or fabric, without causing any undue strain on the yarn, or subjecting the same to any rough usage.

My inver tion primarily is designed for use in connection with knitting apparatus, such as is described and clearly set forth in an application for Letters Patent on a knitting apparatus. filed by me under date of April *8, 1918, Serial No. 227,271. To this end in the operation of a machine such as I have described in my co-pending application, the intwining or intermeshing of the strands of yarn by manipulation of a series oi the im proved needles. brings about a peculiar mesh, loop or knot, as the case may be, and the production of the desired material.

In the further disclosure of the invention,

reference is to be had to the accompanying drawing, constituting a part of this specification, in which similar characters of reference denote corresponding parts in all the views, and in whichnth hill

Figure 1 is an enlarged side elevation of the needle.

Fig. 2 is an enlarged sectional view take on the line2-2 in Fig. 1.

Fig. 3 is a top planview.

Fig. 4; is a bottom plan view, and

Fig. 5 is a transverse sectional view taken on the line 5--5 in Fig. 1. 1

Referring more particularly to the views, 10 indicates the improved needle, generally. and as it will be clearly understood a pair of such needles reversely disposed, are employed to produce a complete stitch, I will only describe in detail one needle. The

needle 10 consists essentially of a shank or stem 11. circular in cross section, and fashioned at its lower end with a rectangular part 12, whereby the needle maybe securely held in position.

means may be employed for seating the needle in the desired angular position. The upper part of the needle 10 is outwardly curved at 13 relative to the axis of the shank 11, and flattened on one side 14 to aline with the circumferential edge of the needle as will be clearly seen on reference more particularly to Figs. 3 and 4:. Furthermore, it

is to be noted that the curved part 13 projects rearwardly beyond the peripheral edge of the shank 11, so that a recessed part 15 is provided. which forms a seat for the loop carried over thereto by the opposed needle. Approximately at ornear the inner end of the curved part 13, I form an under-cut or notched-out part 16, for the purpose hereinafter explained, and said part 13, is provided with an eye or opening 17. The rear face of the curved part 13, is curved or chamfered. at 18 from the eye 17 to the point or tip 19, and the cross section ofthe needle at this point is segmental, as will be seen on reference to Fig. 5. g

It is to be particularly noted that the under-cut or notched-out part 16 is formed on the same side of the needle as the fiat side 14, and that it is curved both ways from its central part. or, in other words. it is segmentalin cross section both longitudinally and transversely of the shank 11. Further, this under-cut or notched-out part 16 is an essential feature of my invention, as, it provides a free passage for the point 19 of the opposed needle behind the thread or yarn de pending from the eye 17 when the said opposed needle is moved over to pick up the loop formed on the needle 10, and resting at 15. Furthermore, it will be clearly understood that if the notched-out part 13, and chamfered part 18, were not provided, that the point 19 of the opposed needle would enter the thread and cause its rupture or splitting.

.As mentioned heretofore. I particularly employ. my needle in connection with the knitting apparatus shown and described in my co-pending application, but it will of course be understood that the needle may be adapted for various other purposes or mechines that may be peculiarly fitted to handle a needle of this character. Iclaim':

1. A needle consisting of a shank circular in cross section and provided with an eyed arcuateend, said arcuate end projecting be are J nan -athle e 'yond the peripheral edge of the shank and having a flat side alining with the front of said. shank, a ehamfered part from the back of the eye to the needlepoint, and an under- 5 cut notch formed in the shank at the juncture' of the arcuate end therewith.

v4 2. As a new article of manufacture, a needle consisting of a. shank provided with meeeee an a'reuate end, said arcuate end projecting beyond the peripheral edge of the shank, 10 end having an eye therein, and a notch in the underside of the shank at the juncture of the shank and arcuate end.

In testimony whereof I aflix my signature.
